1. The interval joining the points A(-1,7) and B(5,2) is divided by a point P(x,y) in the ratio k:1. The point P lies on the line 5x-4y=1. Find the value of k.
2. Given sinθ=0.4 and θ is acute, write down the exact values of:
b) cos(270-θ)
d) cot(360-θ)
3. Solve for -180°≤θ≤180°
i) cosθ=0.187
iii) 4sinθ+3=0
Thanks!
